Group and team class decision-making activities often focus on demonstrating that "two heads are better than one." Typically, students solve a problem or complete an assessment individually, then in a group. Generally, the group does better and that is what the students learn. However, if that is all such an activity conveys, then a significant teachable moment has been missed. It is often the case that a group member has one or more correct answers that the group did not use, or perhaps even outscores the group. The simple activity described here provides an opportunity to discuss a number of reasons that can cause such conformity to happen, integrating several areas of human psychology and behavior, and then segue into techniques to prevent it.
